Welcome !!

like Buyer, Volkswagen Group, Leroy Merlin and many others.

is buyer a company or was it bayer ? :p

I think I will make a whole series of posts on how to use Google Spreadsheets in a non-standard way for the tasks of a manager, marketer, SEO specialist, and even as a no-code way to create a network of affiliate websites.

Really cool ! I'm sure other excel experts like @paulag would find it interesting.

In general, I believe that the ability to work with spreadsheets and make slides are the most important skills for any modern business person.

Being someone who sucks at slides, could you give some pro tips ? Like where do you find a good template or do you built it yoursef, are you using powerpoint, keynote or google slides ? What are the most common errors you see in slides ?
